Tea Party Protesters Protest D.C. Metro Service - Washington Wire - WSJ
Evidently the Teabag-Birfers feel their 9/12 unity protest was derailed by sub par service on Metrorail. Some complained that Metrorail didn't increase capacity beyond normal weekend levels to accommodate the tens of thousands of protesters who came out. They didn't plan on requiring such a high level of government service for their anti-government rally. Of course none of them will walk away from this thinking Metro deserves a dedicated funding mechanism. Because that is socialist.
